FRIDTJOF JEBSEN, BERGEN, NORWAY, ASSIGNOR OF ONE-HALF TO GEORGKIRKEGAARD, OF BROOKLYN, NEW- YORK. j

BOTTLE-STOPPER.

To (ZZZ whom it may concern.-

Be it known that I, FRIDTJOF JEBsEN, a

. subject of the King of Norway, residing at Bergen, Norway, haveinvented certain new and useful Improvements in Bottle-Stoppers, ofwhich the following is a full, clear, and exact description. I

My invention relates to a cap or stopper for receptacles, and pertainsparticularly to that class in which the cap is capable of being removedand replaced upon the receptacle, so as to reseal the same after aportion of the contents have been removed or it is desired to use thevessel for any other purpose. A receptacle-closure adapted to satisfythe foregoing purposes forms the subject of Letters Patent of the UnitedStates, No. 796,734, granted to Georg Kirkegaard. In this patent the capis held upon the bottle by depending fin ers, with which a clamping-ringis-engaged or pressing the fingers into locking engagement with thebottle.

The principal object of the present invention is to render theKirkegaard stopper .more convenient to manufacture, apply, and

operate.

, A further object of the invention is' to render the Kirkegaard stoppermore efficient and more durable.

, With these and other objects in view my invention consists in theconstruction, combination, location, and arrangement of parts,

all as will be more fully'hereinafter described,

' as shown in the accompanying drawings, and

finally particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side view of a cap or stopper embodyingthe principles of my invention. Fig. 2 is a bottom view of the same.Fig. 3 is a sectional view. Fig. 4 1s a detail view of the form ofclamping-ring which I employ. Fi 5 is a bottom view of the cap with thec amping-ring removed. Fig. 6 is a sectional view showing somesIightlymodified features of construction. Fig. 7 is a detail viewof theslightly-modified clamping-ring. Fig. 8 is a view similar to Fig. 5,showing the slightly-modified cap with the clamping-ring removed; andFig. 9 is a side elevation of the neck of a bottle to which my'cap maybe applied. Fig. 10 is a view similar to Fig. 1, except that a'flangedclamping-ring is employed.

Specification of Letters Patent.

Application filed December 9, 1905. Serial No. 291,061.

Patented March A perfectly eflective and satisfactory per must not onlybe capable of efiicienty's 5 I sealing the bottle and easily removableby the purchaser, but should be capable ofits initial attachment withthe least possible amount of trouble or manipulationby-wills yconstitute the bottling concerns, who lar e purchasers. The cap sh 05and not liable to break or bend by" careless manipulation or-ordinaryWear. In ca out the resent invention- 1 provide-means for securing thesedesirablefeatures:

Referring now to the drawingsan to; he

various views and reference-signs appearin thereon,rin which like-partsare deslgnate by the same reference-si n wherever they ocs cur, 1-denotes aca preferably form 1159f sheet metal, with aependingcircumiferen tial rim-which is notched, oast grs 2 withintermediate-separating: Each of the fingers 2 conyen entlfli r mm;atits lower en in a lateral projection or X-'- tremiigl l, so that theprojections of Lthe. rious gers' radiate outwardly frqmga o ,7 moncenter coaxial with'the centeroftheea Inaddition to the lateralprojections d also/be durabl' that the different ribs radiate in-asingleplaiie n;

this way there is provided an intermediate guided to ,move.

tioned and having the inclined or eccentric surfaces 7 similar thereto,but having terminal notches 8 at the be inning of each cam oreccentricsurface 7. I; ach of the notches 8 is of aform and size to receive thefingers 2, which initially lie closely therein in'a'man ner and for apurpose which will be later more particularly explained. I also pro-.which is parallel to but.oppo sitefrom; thef, f= plane oftheprojections or extremities 4. In K);-

f '8 5 space, in which a clam ing-ring may be.

6 in 'cates a practical form of clamping-ring generally similar'to thatof the Kirkegaard patent above men-' vide astop 9 upon theclamping-ring, conveniently formed integral therewith, by

punchin'g'up a portion of the metal of which e00 the ring is formed. Therelation of this stop 9 is such as to contact with the sides of thepiojections or extremities 4 of the depending gcrs, so as to limit thecircumferential movement of the rin The 6 eration of this form I o of myinvention is as f0 ows: The parts are originally assembled with thefingers 2 in the its exterlor surface.

notches 8 of the clamping-ring, and when the stopper is initiallyconstructed the fingers have sufficient outward resiliency to closelybear against the bottoms of the notches 8, so that the cap andclamping-ring are held tightly together and the fingers are spreadsufficiently apart to easily pass over the top of any bottle to which itis desired to apply this stopper. This condition is a desirable one whenthe stoppers are originally handled by the bottling firms, since it isinsured that they may be engaged on the bottles with. the least possibleamount of trouble and manipulation. After the ring has been once turned,so as to tighten the fingers, they do not again have sufiicient outwardresiliency to closely enter the notches 8, so that when thepurchaser-removes and applies the stopper the cam will turn freely.

In Figs. 6, 7, and 8 I have illustrated a form of my invention in whichsome of the details are slightly modified. The clamping-ring 6 is hereshown with a depending peripheral. edge 10, which may be milled upon Thepurpose ofthis construction is to give a larger bearing-surface for theengagement of the fingers in turning the ring. Another feature ofdifference in this form of construction lies in the ribs 5, which arehere made in the form of embossed rotuberances rather than a simpleturned lip or flange, as in the form of construction previouslydescribed. The details of construction may be otherwise modified andstill fall within the spirit and 800 e of the invention, and I do not,therefore, esire to be limited or restricted to the particular featuresshown.

In Fig. 10 the clamping-ring with depending flange 10 is illustrated inconnection with against vertlcal movement by said the. cap constructionof Figs. 1 and which constitutes my preferred modification.

What I claim 1s- 1. A stopper comprising a cap with depending fingersand lntermediate walls having ribs thereon and a clamping-ring supportedby said fifigers and ribs.

2. A stopper comprising acap having depending fingers with intermediatewalls having annular lips or flanges thereon constituting ribs, and aclamping-ling held in proper relation by said ribs and fingers.

3. A stopper comprising a cap having depending outwardly-resilientfingers, anda clamping-ring having eccentric camsurfaces and additionalnotches for receiving the fingers. v

4. A stopper comprising a capha'ving depending fingers, and intermediatewalls with projections thereon, and a clamping-ring having a dependinperipheralfl'ange milled on its exterior sur ace and held in position bysaid projections and fingers.

5. A stopper com rising a cap having depending fingers; an a (glaming-ring havin a depending peripheral. flange and supggrte ers butcapable of rotary movement thereoiito clamp the cap in placeon a bottle.

6. A stopper comprising a cap having depending fingers, a clampm 'sringhaving a orizontal portion rovide with circum ferential grooves a aptedto engage said fingers and with a vertical peripheral flange,substantially as described.

In witness whereof I subscribe my signature in the presence of twowitnesses.
